The invention relates to the technical field of display equipment, and discloses a pixel compensation circuit layout structure and a virtual reality display device. In the pixel compensation circuit layout structure, a first light-emitting signal line, a second light-emitting signal line and a scanning control signal line are sequentially arranged in parallel; a seventh thin film transistor, a fifth thin film transistor, a second thin film transistor, a first thin film transistor and a third thin film transistor are sequentially arranged in the direction from the first light-emitting signal line to the scanning control signal line, and the second thin film transistor and the first thin film transistor are located between the second light-emitting signal line and the scanning control signalline; and a sixth thin film transistor and a fourth thin film transistor are located on the same side of the second thin film transistor, the sixth thin film transistor and the fifth thin film transistor are arranged side by side, and the fourth thin film transistor and the third thin film transistor are arranged side by side. The layout can greatly reduce the number of via holes, reduce the pixel occupation space of the circuit, and improve the PPI of the product.
Description
technical field [0001] The invention relates to the technical field of display equipment, in particular to a pixel compensation circuit layout structure and a virtual reality display device. Background technique [0002] Virtual reality VR products require high pixel density (PPI) in order to improve clarity, which means that each pixel space is small, and a good layout method can save a lot of space. However, in the existing pixel compensation circuit of the organic light emitting diode display, the number of thin film transistors (TFTs) is relatively large, the layout is complicated, and there are many via holes occupying space, which affects the improvement of the PPI of the product. Contents of the invention [0003] The present invention provides a pixel compensation circuit layout structure and a virtual reality display device. The above-mentioned pixel compensation circuit layout structure can greatly reduce the number of via holes when connecting each thin film tra...
